I aways delete the preversion first as norton and some other programs tend to get buggy. The upgrade version will still install ok if pre version is deleted. I am still looking for the best price for NIS 2006.
Thanks for your responses I have tried safe mode and it does appear but will not allow me to remove it Safe mode has several options, including going back to the last succesful configuration. Any suggestion which one I should use?bbmf
dibblydufuss It is not a new machine. It is a philleps which until I downloaded the new norton worked normally. AS teh donwloan installed it did offer to delete previous version which I accpeted. I think this has been done. In safe mode the programme appears in add/remove but says I have to open in nomral mode then delete it.Trouble is I cannot use normal mode just get desktop only, no icons or task bar! Shall I use system restore or go back to last working configuration -one option in safe mode?
